This JPL Rapid Mission Architecture (RMA) study was not a mission concept study of a single mission, but instead was an architectural-level study of a set of missions to the Neptune system and, for some, continued travel to a Kuiper Belt Object (KBO). It was commissioned by three Planetary Science Decadal Survey Panels: Giant Planets, Satellites, and Primitive Bodies, whose diverse sets of science priorities made tailoring architectures to the science priorities particularly challenging. The... Topics: Neptune, Triton, Kuiper Belt Object, NASA, Decadal
What is a planet? This question has been pondered by many since the early Greeks came up with the word "planetes". Since then the number of "planets" in our solar system has fluctuated, sometimes numbering as high as 15, before it was determined that some were actually asteroids. Topic: A fascinating travel along the "Kuiper Belt highway" at 100mph to explore the far reaches of our solar system that discovers how vast our corner of the galaxy really is.

The unexpected discovery of remanent crustal magnetism on Mars was one of the most intriguing results from the Mars Global Surveyor mission. The origin of the pattern of magnetization remains elusive. Correlations with gravity and geology have been examined to better understand the nature of the magnetic anomalies. In the area of the Martian dichotomy between 50 and 90 degrees E (here referred to as the Ismenius Area), we find that both the Bouguer and the isostatic gravity anomalies appear to...

Terra MODIS 250 m observations are being applied to a Suspended Sediment Concentration (SSC) algorithm that is under development for coastal case 2 waters where reflectance is dominated by sediment entrained in major fluvial outflows. An atmospheric correction based on MODIS observations in the 500 m resolution 1.6 and 2.1 micron bands is used to isolate the remote sensing reflectance in the MODIS 25Om resolution 650 and 865 nanometer bands. SSC estimates from remote sensing reflectance are... Topics: OCCULTATION, TRITON, PLUTO (PLANET), SATELLITE ATMOSPHERES, PLUTO ATMOSPHERE, ASTROMETRY, KUIPER...
We describe how the coherence function, a Fourier frequency-dependent measure of the linear correlation between time series measured simultaneously in two energy channels, can be used in conjunction with energy spectra, power spectra, and time delays between energy channels to constrain models of the spectrum and variability of X-ray binaries. Here we present a procedure for estimating the coherence function in the presence of counting noise. We apply this method to the black hole candidates...

Head movements in the sagittal pitch plane typically involve off-axis rotation requiring both vertical and horizontal vergence ocular reflexes to compensate for angular and translational motion relative to visual targets of interest. The purpose of this study was to compare passive pitch VOR responses during rotation about an Earth-vertical axis (canal only cues) with off-axis rotation (canal and otolith cues). Methods. Eleven human subjects were oscillated sinusoidally at 0.13, 0.3 and 0.56 Hz... Topics: HELIOSPHERE, ICE, COSMIC RAYS, COLLISIONS, SPACE WEATHERING, SPUTTERING, SOLAR SYSTEM, VOYAGER 1...
With safety designed from inside out and outside in, see how NASA has used Radioisotope Power Systems, or RPS, for more than 20 missions over the last 50 years. Discover the advantages of an RPS that allow spacecraft like Voyager to still do important scientific maneuvers after being in the extreme environment of space for 30 years! Find out where an RPS could take us in the future. Topic: NASA, NIA, eClips, Launchpad, High School, Video, Education, Mathematics, Technology, Science,...
